    I just picked up an '83 CR480R with front and rear disk brakes. Front end is from an '89 KX250 (works great) and the rear is a hodgepodge of a modified stock swingarm, KTM brake caliper, and LC4 rear wheel. It's functional but kind of messy. Has anyone done a rear disk brake conversion on a CR480R or similar? I wonder if something like a stock LC4 (right-side chain) swingarm will fit.

    On that note, has anyone put modern forks on an old bike like this?

    If done right I think that rear disk would be a nice upgrade for the ol' CR :evil I hate the rear brake on my 84 not because it lacks in performance but because the aluminum arm is a rock magnet and gets bent frequently.

    With machine work fork upgrades are unlimited. A popular swap is the 87 CR cartridge forks. They swap over easily and have a reputation for being one of the best forks ever made. I have them on my 84 500 and couldn't be happier.

    The rear as it is, with the hacked-together setup, works really well. That is, of course, until my brake pedal fell off yesterday. I found all of the parts save for the but holding the pedal to the frame. I'll have to find a new nut at the hardware store-- with some loctite this time!
